SEWING-MACHINE-BELT PACKAGE em) METHOD or MANUFACTURE.

Application filed December 17, 1921. Serial No. 523,142.

To all whom, it 'lml-g concern Be it known that l, GUSTAV A. CAHLSON, a citizen of the United States, residing at Chicago, in the county of Cook and State o Illinois, have invented a new and useful Improvement in Sewing-Machine-Belt Pack ages and Methods of Manufacture, of which the following is a specification.

This invention relates particularly to a belt package and a method of packaging .helts. The invention is particularly useful in connection with the merchandizing of sewing-machine belts.

The invention. is illustrated in its preferred embodiment in the accompanying drawing, in which Fig. 1 represents a vertical sectional view illustrating the manner in which a sewingmachine belt is wound on a shaft between two packaging-disks; Fig. 2, a broken plan view of the means shown in Fig. 1; Fig. 3, an elevational view of a package with the belt wound therein, this View showing the manner in which a sealing-strip is applied to connect the disks together and provide a circumferential wall; Fig. 4, a broken sectional view taken as indicated at line 4 of Fig. 3; and Fig. 5, a broken sectional view taken as indicated at line 5 of Fig. 3.

In the illustration given, A represents a belt-winding shaft; B, a package for the belt: and C, a sewing-machine belt.

The package comprises a pair of stiff disks '1 which preferably are composed of cardboard: and a flexible binding-strip 2 which is folded over the peripheral portions of the disks and secured thereto by a suitable adhesive.

The method of packaging the belt will be readily understood. The disks 1 are provided centrally with a shaft-opening 1 and with key-slots 1 The disks are slipped onto the shaft A, which is provided with keys 3 which are received by the slots 1, the disks thus being removably keyed to the shaft.

The belt C is provided at one end with a hook 5 which engages one of the keys or splines 3. The winding of the belt between the disks 1, which are suitably spaced with respect-t0 each other, is effected by rotating the shaft, while the belt C is held taut. The

space between the disks is such that the belt is wound in evoluteform in a single plane. \Vhen the winding of the belt is completed, the binding-strip 2 is applied. This may be plete, it may be'slipped ofi' the'shaft.

done by gumming one" end of the-stripto the marginal portions of the disk and then slowly rotating the shaft to cause the pack age to rotate, while the operator folds the lateral edge portions of the strip over the margins of the disks and cements them-in place. 'A. previously gummed strip, suitably moistened, may be employed, and, by the ineans'described, may be readily applied to seal the package. After the package is con1- InFig. 2, the pasteboard disks 1 are shown clamped between two metal disks 6 which are mounted on the shaft or-arbor A. One of the disks 6 1s shown provided with a transverse cut or slot'6 in one of its sides, g ving the effectof a split ring, whereby the disk is clamped on the end portion of the. arbor. The disk may be readily removed, however, to enable the package to be withdrawn from the arbor. The pasteboard disks 1 are preferably provided with segmental openings 1 which are separated from the central opening 1 by the hub portions 1 of the disks.

The openings 1 enable the coiled belt to be viewed. The outsides of the pasteboard disks 1 may be covered with paper and suitably ornamented, or may carry such advertising designs (not shown) as .may be desired. The form of the package itself is novel and presents a pleasing design. The

belt may, if desired, be removed from the package by unwinding it thru the central opening of one of the cardboard disks. This may be accomplished by withdrawing the inner end of the belt thru the central opening and then paying out the belt thrn the central opening. The belt may be in spected and then returned by a reverse coiling operation, if desired.

The improved package is simple, cheap and distinctive; and the packaging operation may be performed very cheaply. The improved package not only affords a distinctive design of package but also enables the belt to be viewed thru the lateral openings 1. j g
